- v Application filed a rn'aa, 1931 Serial No. 532,330, I

My invention relates to boats, more particularlyto boats of theamphibian type, and

it consists in the constructions, combinations,

and arrangements herein shown and described. H 1 t i A primary purposeof my invention is to provide a boat which will have means'zfor gettingofi the ground if unfortunate enough to get aground in shallow water,thatwill m be able to navigate shallow water, and that will be able to'go to and from bodies of water.

A further obj ect of my inventionis to prov vide a boat of the typedescribed that is able to raise its hull-above water so that the samemay be cleaned, repainted, repaired or inspec'ted While theboat isafloat, thus avoid ing the expense of going to dry-dock or onto marineways. r A still further object of my invention is m to provide a boathaving'verygreatstability,

thus enabling the same to proceed under power in heavy weather. I 7

A yet further object of my invention is to I provide a-device of thetype described which has few parts, is-simple to manufacture, and

does not get out of order easily, 1

Other objects and advantages will appear as the specification proceeds,and the invention will be more particularly defined in the appendedclaims. My device .is illustrated in the accompanying drawings forming apart of this application, in which Figure 1 is an elevational view of myinvention, r 5

Figure 2 is a longitudinal sectionalview of my invention with partsthereof-shown in elevation, V

Figure 3 is an 'end elevational view of 'a part of my invention with theparts in one operative position, r

Figure 4 is a similar view withthe parts in another operative position,

-igure'5is a fragmentary detailed view of aportion of the device, and IFigure 6 is a partlyschemat'io and partly detail view of another portionof the device. In carrying out my invention, I make use 250 of an'ordinary'boathull 1, equipped with an engine, 2, or other suitablepower means, or

This frame member, 18, supports between its 'tion and depression of thedrum members, 9.

adapted for manual propulsion in the case of smallboats of thistypewhich maybe operated by hand without any engines whatsoever. c Thisboat hull, 1, on either side thereof, is

equipped with a land and sea propulsion means, generally indicated at3,-e'ach of said means consisting of la pivotally mounted frame, 4,swivelled as indicated at 5, to the side of the boat, and, swivellymounting at its opposite end a fra1ne,-'6. This frame, 4, consists ofthe angularly formed side members, 7, having abracing bar, 8, extendingtherebetween. It supports between its side arms, 7, a rotatable hollowhermetically sealed drum, 9, of heavy construction "having on itsperiphery heavy paddle blades, 10, adapted to support the drum whenbrought into contact with the land, or to propel the boat through Waterorcarry it over the land when rotated. For raising and'lowering thedrums, 9, for raising the boatabove the water, as shown most clearlyinFigure 2, as vwell as; for raising the boat to enable the same totravel over land, and for propelling the boat through the water in amost-efficient manner, the frame members, 6, on each side, which in thisem bodiment each consist of a pairof side arms,

11, with a vbracing arm, 12, are each con-nected to a hoist, comprisingthe frame member, 13, secured to the side of the boat .as indicat ed at14 and 15, and having a bracing arm,

16, between, the;arm members, 17 thereof.

arm members,,l7, adruin hoisting mechanism, 18, which may be ofsuitabIe-Construction, but which is shown in thisembodiment asconsisting of a rotatable drum member, 19,, havinga manual,means,20,,for the rotation thereof, and a pawl and ratchet mechanism shown at2-1 and 22, for-securing the drum in a desired position. The bracingarm, 16, of the frame is equipped with a,pul1ey, 2'3, mounted as shownat 24. About the pulley and thedrum the cable, '25, is passed, the endsofIsaid' cable being connected to the" frame member, 6, as shown at '26and 27. It

is obvious from'fthis description that rotation of'thehoisting drum willbring about ;elevam0 sprockets, 30, are mounted on the hollow drivingshaft, 32, which bearingly supports the shafts, 5, pivotally supportingthe frames, 4c.

These hollow driving shafts are driven by the motor, 2, through thegeared connection, 33.

A clutch, 34, enables the operator to apply or means of rotation of thehoisting means thus raising the boat above the water supported *by thedrums. The buckets at the end of the withdraw the power as desired.

The shaft, 32, is rotated in one direction by gears, 35 and 36, whichare moved into engagement by means of clutch lever, 37, sliding thegear, 35, into mfesh'with gear, 36, the gear 35,- being splined or keyedon shaft,- 32. It is rotated in the opposite direction by means ofinter-engagement between gears, 36 and 38, gear 38 being similarlysplined or keyed on shaft, 32, and operated to its positions by means ofclutch lever, 39.

For enabling the operator to drive one of the drums while the otherremains stationary,-

clutches, 39a and 39?), are provided between each of said drums andthegears, 35 and 38, re spectively. It can readily be understood thateither of the drums can be thrown out of con- .nection with the drivingmeans by operation depression of the drums, 9, I suspend at either endof said boat buckets, 40, which will prevent tilting motionsof the boatabout the drums in a manner easily understood.

- From'the foregoing description, the use and operation of my device iseasily understood. When the operator desires to utilize the invention asa boat, he simply elevates the drums by means of the hoisting apparatusand fixes the same in a desired position with the pawl and ratchetdevice. It is noted that this pawl and ratchetdevice is adapted toprevent motion of the hoist'in either direction of rotation. He thenoperates clutch, 34, and one of the gears, 35 or'38, into engagementwith gear, 36, in accordance with which direction he wishes the boat totravel. It can readily be understood that the boat will be propelled bythe blades on the drums in the desired direction. I

'When the operator desires to turn the boat either in the water or uponthe land while the boat is in motion either in a forward or backwarddirection, he simply operates one of the clutches, 39a or 396, torelease either the left or right drum, allowing the other drum torotate, thus turning the boat. He may control the speed-of the boat ineither direction by means of the rheostat, 39c.

It is understood that, of course, any suit? able conventionaltra-nsmissioncontrol could be utilized in place of the clutch systemshown by applicant.

I It is also understood that the drums will act as stabilizing means tokeep the boat afloat and topropel it in the proper direction duringstorms and heavy weather.

When the operator desires to elevate the boat above the water forpurposes of cleaning the hull of the same or for other operations, hesimply depresses the drums by boat being filled with water will preventtilting of the same about the drums.

When the operator desires to use the device as a land vehicle, he needsimply operate the hoist to lowerthe drums as inflthecase of elevatingthe'boat above the water and set the drums in motion in the desireddirectionby means of the gears, 35, 36, and 38, and the clutch, 34. Ofcourse, during this operation, additionalv supporting means must be sup:plied for either end ofthe boat to prevent thesame from dragging. Thiscan easily be taken care of by attaching the same to another vehicle orusing an additional carriage (not shown) under either end.

It is. understood that in the case oflargeboats a power hoist might beutilized without deviating from my invention. It is further understoodthat if desired the drums may be driven by a separate power means toenable the operator to utilize the same by moving oneqor the other forsteering of the boat or vehicle. 1 A

It is thus seen that I have provided a boat which is adapted to travelon land or navi gate' on' sea and which is further adapted to elevateitself above the sea when desired.

It is further seen that I have provided a boat that is adapted forstable operation'during heavy weather, that can get off the ground ifunfortunate enough to get agroundin shallow water, and raise itself upon the shore on its own power when necessary. r What I desire to claimand secure by Let-. ters Patent is:

1. A boat, comprising a hull, power means positioned in said hull,rotatable drums on either side of said hu'll,;propulsion blades on saiddrums, pivotal arms supporting said drums, and means for oscillatingsaid pivotal arms to depress and elevate said-drums for raising andlowering said boat, consisting; of members pivotally mounted to saidarms, hoistingframes secured to the hull, drums secured to said hoistingframes, pulleys se' cured to said hoisting frames, endless flexiblemembers secured at their ends to said pivotally mounted members andtrained about their respective pulleys, and drums, means for rotatingsaid drums, and means for securing said drums in a desired position. v

2. A boat, comprising afhull, drums posi tioned on either side of saidhull and having propulsion blades thereon, pivotally mounted arms formounting said drums, means for rotating said drums for propelling theboat,

and means for raising and lowering said drumsto raise and lower the hullrelative to the water, consisting of a hoist pivotally related to theends of said arms, and pawl and ratchet means associated-with said hoistfor securing the same in a desired position.

3. A boat, comprising a hull, drums positioned on either side of saidhull, means for raising and lowering said drums to raise and lower thehull, and buckets connected to either end of said hull to preventtilting of said boat about said drums when said hull is in the elevatedposition.
